Ukuqondiswa kokuthuthukiswa kwe-alumina ecushiwe
Entuthukweni entsha ethokozisayo, abacwaningi baye bavula ngempumelelo i-aluminium, bavula amathuba amaningi okusetshenziswa ezimbonini ezihlukahlukene.Lokhu kuphumelela, okubikwe ocwaningweni lwakamuva olushicilelwe kumagazini i-Nature, kunamandla okuguqula indlela i-aluminium esetshenziswa ngayo ...Funda kabanzi -
Ukusetshenziswa kwe-ZSM ye-molecular sieve njenge-catalyst ye-isomerization
I-ZSM molecular sieve iwuhlobo lwe-crystalline silicaluminate enobukhulu obuhlukile bembotshana nokuma kwayo, esetshenziswe kabanzi ekuphenduleni kwamakhemikhali okuhlukahlukene ngenxa yokusebenza kwayo okuhle kakhulu kwe-catalytic.Phakathi kwazo, ukusetshenziswa kwe-ZSM ye-molecular sieve emkhakheni we-isomerization catalyst has attra...Funda kabanzi -
I-acidity engaphezulu ye-ZSM molecular sieve
I-acidity engaphezulu ye-ZSM ye-molecular sieve ingenye yezakhiwo zayo ezibalulekile njenge-catalyst.Le acidity ivela kuma-athomu e-aluminium kuhlaka lwamathambo lwesisefo, olunganikeza ama-proton ukuze akhe indawo ene-protonated.Le ndawo ene-protonated ingabamba iqhaza ezinhlobonhlobo zokusabela kwamakhemikhali...Funda kabanzi -
Umthelela wesilinganiso se-Si-Al kusihlungi se-molecular ye-ZSM
I-Si/Al ratio (i-Si/Al ratio) iyimpahla ebalulekile ye-ZSM molecular sieve, ebonisa okuqukethwe okuhlobene kuka-Si no-Al esisefweni samangqamuzana.Lesi silinganiso sinomthelela obalulekile emsebenzini nasekukhetheni kwe-ZSM ye-molecular sieve.Okokuqala, isilinganiso se-Si/Al singathinta i-acidity ye-ZSM m...Funda kabanzi -
Umthelela kanye nomsebenzi we-ejenti yesifanekiso ekuhlanganisweni kwesisefo se-molecular ye-ZSM
Enqubweni yokuhlanganiswa kwe-sieve yamangqamuzana, i-ejenti yesifanekiso idlala indima ebalulekile.I-ejenti yesifanekiso i-molecule ye-organic engaqondisa ukukhula kwekristalu yesisefo samangqamuzana ngokusebenzisa ukuxhumana kwe-intermolecular futhi inqume isakhiwo sayo sokugcina sekristalu.Okokuqala, i-ejenti yesifanekiso ingathinta...Funda kabanzi -
I-ZSM molecular sieve
I-ZSM molecular sieve iwuhlobo lwe-catalyst enesakhiwo esiyingqayizivele, esibonisa ukusebenza okuhle kakhulu ekuphenduleni kwamakhemikhali amaningi ngenxa yokusebenza kwayo okuhle kakhulu kwe-asidi.Okulandelayo ezinye zezisusa nokusabela okungase kusetshenziselwe izisefo ze-molecular ZSM: 1. I-Isomerization reaction: ZSM molecular si...Funda kabanzi -
Ukusetshenziswa kanye nokuhlanganiswa kwe-ZSM-5 ye-molecular sieve
I. Isingeniso I-ZSM-5 i-molecular sieve iwuhlobo lwe-microporous material enesakhiwo esiyingqayizivele, esiye sasetshenziswa kabanzi emikhakheni eminingi ngenxa yezindawo zayo ezinhle zokukhanga, ukuzinza kanye nomsebenzi wokuvuselela.Kuleli phepha, ukusetshenziswa kanye nokuhlanganiswa kwe-ZSM-5 ye-molecular sieve izofakwa ngaphakathi ...Funda kabanzi -
Ucwaningo ngobubanzi bokusetshenziswa kwe-silica gel desiccant
Ekukhiqizeni nasekuphileni, ijeli ye-silica ingasetshenziswa ukomisa i-N2, umoya, i-hydrogen, igesi yemvelo [1] njalonjalo.Ngokusho kwe-asidi ne-alkali, i-desiccant ingahlukaniswa ibe: i-acid desiccant, i-alkaline desiccant kanye ne-desiccant engathathi hlangothi [2].Ijeli ye-silica ibonakala ingomisi ongathathi hlangothi obonakala bomisa i-NH3, HCl, SO2, ...Funda kabanzi
